PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Valenti et al., ATel #4037; http://www.pessto.org ), reports the following supernova classifications. Targets were supplied by Pan-STARRS (see Valenti et al., ATel #2668) and DECam (Forster et al., ATel #5949). All observations were performed on the ESO New Technology Telescope at La Silla on 2014 Mar 7, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and GELATO (Harutyunyan et al., 2008, A&A, 488, 383). Classification spectra can be obtained from http://www.pessto.org (via WISeREP).

(1) Narrow emission lines of Halpha, Hbeta, [O II], [O III] and [S II] on a blue continuum. The transient is in a spiral arm, clearly separated from the centre of the well-resolved host galaxy.
(2) EMILIA has a blue continuum, with narrow Halpha and [O II] 3727 Ang emission.
